Stability problems with Amontec JTAGKey+libftd2xx

Development Boards MicroMod
1

Hello!

I have installed svn r121 with libftd2xx0.4.10. I use it with an lpc2292. This is how I installed openocd:

$ cd openocd
$ ./bootstrap
$ ./configure LDFLAGS=-L$FTDDIR --enable-ft2232_ftd2xx --with-ftd2xx=$FTDDIR
$ make clean all tags

The config I use is based on openocd/doc/configs/arm7_ft2232.cfg. The only modification is that I use run_and_init and increased jtag_speed to 200 (but changing this value dont make a difference):

#daemon configuration
telnet_port 4444
gdb_port 3333

#interface
interface ft2232
ft2232_device_desc "Amontec JTAGkey A"
ft2232_layout jtagkey
ft2232_vid_pid 0x0403 0xcff8
jtag_speed 200
#use combined on interfaces or targets that can't set TRST/SRST separately
reset_config trst_and_srst srst_pulls_trst

#jtag scan chain
#format L IRC IRCM IDCODE (Length, IR Capture, IR Capture Mask, IDCODE)
jtag_device 4 0x1 0xf 0xe

#target configuration
daemon_startup reset
#target <type> <startup mode>
#target arm7tdmi <reset mode> <chainpos> <endianness> <variant>
target arm7tdmi little run_and_halt 0 arm7tdmi-s_r4
target_script 0 reset h2222_init.script
run_and_halt_time 0 30
#working_area 0 0x40000000 0x40000 nobackup

#flash configuration
flash bank lpc2000 0x0 0x40000 0 0 lpc2000_v1 0 14765 calc_checksum
flash bank cfi 0x80000000 0x200000 2 2 0

Then I issue following commands:

halt
mdh 0x80000000 0x200000

Then, after a while the deamon stops. With dmesg I can see that something nasty happened to the JTAGKey:

usb 2-2: reset full speed USB device using uhci_hcd and address 20
hub 2-0:1.0: port 2 disabled by hub (EMI?), re-enabling...
usb 2-2: USB disconnect, address 20
usb 2-2: new full speed USB device using uhci_hcd and address 21
usb 2-2: new device found, idVendor=0403, idProduct=cff8
usb 2-2: new device strings: Mfr=1, Product=2, SerialNumber=3
usb 2-2: Product: Amontec JTAGkey
usb 2-2: Manufacturer: Amontec
usb 2-2: SerialNumber: 32P6NXSJ
usb 2-2: configuration #1 chosen from 1 choice

The last output from openocd is

Any ides what happens here?

This seems to be either a kernel driver problem or USB hardware problem.

usb 2-2: reset full speed USB device using uhci_hcd and address 20

hub 2-0:1.0: port 2 disabled by hub (EMI?), re-enabling…

usb 2-2: USB disconnect, address 20

Theese messages are mostly found in discussions about old versions of the kernel or hardware with special USB drivers.

What kind of system, kernel and hardware are you using ?

I am not aware that I have anything very old or broken here.

Hi

Nothing strange with the configuration.

Does this happen everytime, and at the same place?

Can you run openocd under a debugger and place a breakpoint at

ft2232.c:365, just before the program exits.

A backtrace from this point could be very helpful.

I am still a bit supicious about USB hardware, my system usually only misbehaves when connecting to many things to cheap USB hubs.

Nope. It is pretty much random.

For sure:

I am still a bit supicious about USB hardware, my system usually only misbehaves when connecting to many things to cheap USB hubs.

I'll probably purchase an external hub and a pci card. Maybe the problem will go away with one of them.

Today the external usb hub (with its own power supply) arrived. This solved the problem.

Hi jw,

thanks for the problem description. I have the same problem with my jtag debugger (oocdlink.joernonline.de) :?

I will try a active usb hub.

Okay, i got a usb hub.

I my case a passive hub improved the stability of my debugger very much. I made a test with the serial interface. Without the hub and 115.2 KBaud the FT2232 only worked 30 seconds. Now with the hub it runs over an hour @ 1MBaud.

regards

Joern
